2. Why did study authors look @ Gauteng + not the entire SA? 1. SA's #Omicron outbreak started in Gauteng, so there's data 4 a longer period than other provinces 2. They looked @ the 1st 4 weeks of #Omicron + compared it to the same periods for Wave 2 (Beta), Wave 3 (#Delta)
3. From when to when were the 1 month periods of the waves?
- Wave 2 (Beta): 29 Nov-26 Dec 2020
- Wave 3 (#Delta): 2 May-29 May 2021
- Wave 4 (#Omicron): 14 Nov-11 Dec 2021
It’s when health workers try to trace the people 1 infected person could potentially have infected by asking the infected person who they have been in contact with and getting those people to then test or isolate if they test positive.
In short: It’s too expensive for what we get out of it, so we spend a lot of money 4 very little gain (gain = picking up infected people + stopping them from infecting others). We could use the money better on other stuff/diseases.
JUST IN [Thread]: 1. @HealthZA disagrees with the US government's CDC's decision to recommend #mRNA jabs above #JnJ (because of rare side effects) - we'll continue using JnJ 2. The US = abundance of jabs (100 mil + ready for use), so they can afford 2 be choosy.
2. How safe is #JnJ? 1. @MRCza analysed safety data from the #Sisonke study (which uses #JnJ) 2. Serious side effects were rare and occurred in only 129 out of about 500 000 #HealthWorkers in the study
3. What does #Sisonke data tell us about mild #JnJ side effects? 1. The commonest side effects = headache, body aches, pain @ injection site, fever 2. Most side effects = occurred within 48 hours of vaccination
BREAKING [Thread] 1. @SAHPRA1 has approved a 2nd dose of #JnJ and heterologous (mix/match) booster for adults:
1. If u had a JnJ jab, u can get a booster @ least 2 mnths after 1 JnJ shot 2. If u had a #Pfizer jab, u can get a JnJ booster @ least 6 mnths after a 2nd Pfizer jab
2. Does @SAHPRA1's approval mean you can have a #Pfizer booster after a #JnJ shot?
NO. It’s only the other way around (a #JnJ booster after a 2nd #Pfizer shot) that has been approved as a “mix and match” booster.
3. Why does @sahpra1’s “mix and match” approval not allow for a #Pfizer booster after a #JnJ shot?
Pfizer hasn’t submitted data to Sahpra for approval (#JnJ submitted the data 4 a #JnJ booster after #Pfizer).
